VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 366,693, dated July 19,i887.

Application tiled October 13, 1886. Serial No. 216,175. (No model.)

To all whom it may concern:

Be it known that I, GARDNER M. SHERMAN, residing at Springfield, in thecounty of IIampden and State of Massachusetts, haveinvented certain newand useful Improvements in Deodorizing Evaporators, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to deodorizing ordisinfecting vessels in which achemical fluid is placed, and from which the vapors of evaporation areallowed to escape into the room, sewer, or other locality to bedisinfected.

lFigure l is a vertical central section of the vaporizing or evaporatingvessel. Fig. 2 is a plan or top view of the head of the retaining jar.Fig. 3 is a section similar` to Fig. l with the cover and tip-stopper ofthe jar lifted. Fig. 4. is a. cross-section of Fig. 2 on line as.

A in the drawings represents a tin or other metallic can, or ajarofglass or earthenware, having ahead, B, which is'provided with acrossbar, C. The crossbar C supports a hollow spindle, D, which is screwthreaded externally and works in a thread in the bar C.

The spindle D is screwed or otherwise attached to cover E, so that therotation of the cover will cause it to be lifted from the rim of thehead B, as shown in Fig. 3.

The tip-stopper F has its seat in the cover E, and is held there by ascrew-thread or in other suitable manner. \Vhen this stopper` is closed,the passage-way through the spindle D is stopped.

G indicates-a porous cup of plaster, having a baserim, l, which rim titsclosely within the cup A. This leaves an annular recess, L, between thecan or jar and the porous cup G.

The cavity Hin the porous cup G may be filled with a carbolic solution,or any other similar chemical in liquid form which is used as adisinfectant. This fluid will slowly percolate through the plaster cup,and the gases of evaporation will risc from the exterior of the cup inthe annular space L. When the cover is tightly screwed down, the gascannot escape; but when the cover is slightly lifted on the spindle D anopeningA is formed all around the edge of the cover, from which openingthe gas may escape into the room.

If it is desired to accelerate the rate of evaporation, the plug I maybe removed from opening-fu1nes is desired, the cover E may be tightlyclosed and the stopper F removed, when the escape ofgas or vapor will beonly through the tubular spindle D.

This apparatus may be used in a sick-room to great advantage, thecapability for regulating the escape of the vapors with great nicetymaking it an excellent device for the purpose. For sewers or cesspoolsthe plaster cup G may be used Without theinclosing-can, and a Very cheapand efficient device is thus produced.

The stopper S may be used with the cup G when the latter is inclosed incan A, when the evaporation must be entirely through the walls of theporous cup.

I claiml. The combination, with the inclosing-jar or can, of the porouscup having a flange near the bottom which fits the inclosing-can, butleaves an annular recess above the same.

2. The combination, with the inclosing-can and the inclosed porous cup,of a cover, and a spindle from said cover engaging a support on the can,by which spindle and support the position of the cover relatively to thecan may be fixed and determined, substantially as dcseribed. i

3. The combination, with theinclosing-can, of the inclosed porous cup, ahollow spindle extending up from the cup, and a stopper at the top ofsaid spindle, substantially as described.

4. The combination of the inelosi'ngcasing having an adjustable coverand a stoppered Ventilating or draft opening near the bottom of saidcasing, said opening communicating with the space between the casing andthe inclosed cup, and the porous cup within but not entirely filling thecasing, substantially as de scribed.

In testimony whereof I affix my signature in presence of two witnesses.
